Walter Martinez was 22 when he was fatally shot in South Philadelphia before dawn on Sunday, October 4, 2009. Witnesses reported seeing several men arguing in Spanish near the corner of South Seventh and McClellan streets at about 4:20 a.m.; during the confrontation one man pulled a gun and fired at close range. Martinez was struck four times in the chest on the 1800 block of South Seventh Street and taken from his nearby home on the 600 block of McClellan Street to Thomas Jefferson University Hospital, where he died at 8:43 a.m.
